A new Web site is home base to a campaign that asks Congress not to act so hastily on bills that the public has no time to review them. Called ReadtheBill.org, the site has launched a new Mystery Busters initiative urging members of Congress to vote against any legislation or conference report that has not been posted on the Internet for 72 hours. Each week when Congress is in session, the site will publish a list of “mystery bills,” including a “mystery bill of the week.”
